Hello Subhadeep Sardar. Thanks for contacting Careers360 and we hope we will be answer your query.

Yes, the JEE Mains and Jee Advanced counselling (though they are totallly two different things), and in fact, I should say, the cutoffs for every college entrance exam in India take admissions to students on the basis of General, OBC-NCL, SC and ST. 

I would like to direct your attention to this Careers360 article for more information about the JEE Mains cutoffs:

Hope this helps you and all the best!
